Like the Internet, this skeleton is made up of a series of tubes. If you don't like rolling small paper tubes, this may not be a good fit for you. My approach has been a bit loose (measure no times, cut twice) so if you are creating this you will have to play around a little bit and find out what works for you.
The whole thing probably took ~40 hours, but some portion of it was trial and error so you could probably cut it by a decent amount. It was very inexpensive to make, and resulted in a reasonable approximation of what I was looking for.
I am no biologist, nor do I aspire to be. I set out to make something that is only recognizable as a bird's skeleton about the size of a crow. Some of the bones are more faithful reproductions than others, but none of them would be mistaken for the real thing. The crow also ended up with 4 or 5 extra vertebrae because that is how long I wanted the neck to be.
Step 1: Materials
To make this skeleton you will need some materials:
- 2 sheets of letter sized paper
- roll of masking tape
- palette for your glue (made of something that won't absorb glue)
- thin sturdy tool for applying glue precisely
- hobby knife
- decent scissors
- white glue
In addition to the hard materials you will also require some reference materials, use the Google Machine, it should provide you with what you need.
